I have always done 50 to 75% weekly water changes, even when cleaning the filter. I have never noticed any type of change in the water parameters from done that. Your water changes should not have any impact on your filter, even when you clean it.

If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease."Not using a quarantine tank is like playing Russian roulette.

Same for me. I always do 50% changes even when I clean the filters and never have any issues. A well seasoned tank should be able to handle a good filter cleaning without trouble.

When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top... KingfisherEverything happens for a reason. Sometimes that reason is you are stupid and make bad decisions. I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.

Yikes, I've done that too on occasion Scotti. Luckily there is little to no beneficial bacteria in the water.

There still would not be any benfit to changing filter media with or without a water change, the two will not effect each other. IMO, you should never change your filter media until it starts to fall apart, reguardless of when you will do a water change.I have filter media going on 4 years old and it still works very well. Can't see me changing it in the next 4 years either. If you maintain you media, it will work for many many years
